Hi wihi nsinya wa nawu wa ku namarhela ka thepi ya PTFE?

Thepi ya PTFE leyi endliweke hi Jiangsu Aokai New Materials, muendli wa xiphurofexinali wa thepi ya PTFE, yi tirhisa xinamarheti lexi twaka ntshikelelo wa silicone (silicone PSA) . Ku namarhela ka silicone PSA ku landzelela magoza yanharhu ya misava hinkwayo ya PSA: ku tsakamisa – ku adsorption – cohesion , kambe endlelo ra yona ri hlawulekile:

1. Ku tsakamisa na ku adsorption ka nyama

Silicone PSA ya PTFE tape i ku hlanganisiwa ka:

·  Raba ya silicone  (yi nyika ku olova na ku olova) .

·  MQ silicone resin  (yi nyika ku tiya na tack) .

Ehansi ka ntshikelelo wo olova, ti silicone rubber chains leti olovaka ti khuluka hiku hatlisa kuva ti tsakamisa micro rough surface ya substrate. Physical adsorption yihumelela hiku tirhisa matimba ya van der Waals xikan’we  na partial hydrogen bonds.

2. Xivumbeko xa 'Xihlala xa lwandle': ku hambanisiwa ka ku namarhela na ku hlangana

Leyi i endlelo ro hlawuleka swinene ra silicone PSA eka PTFE tape:

·  MQ resin (the 'islands') : rigid three dimensional cage ku fana na swivumbeko leswi hangalakeke eka leyara yo namarhela. Tinyika ku namarhela  – mintlawa ya silanol (Si–OH) eka MQ resin yi endla vuhlanganisi byo tiya na swiphemu swofana na nghilazi, nsimbi, na rhaba ya silicone.

·  Silicone rubber (the 'sea') : xiphemu xa polymer lexi yaka emahlweni lexi nyikaka matimba yo hlangana  ku lwisana na ku tsandzeka ka le ndzeni hi nkarhi peeling.Hiku lulamisa ratio ya MQ resin kuya eka silicone rubber, tack  na matimba ya peel  swinga ringanisiwa kahle.

3. Netiweke leyi hlanganisiweke yi ndlandlamuxa ku hlangana

Hi nkarhi wa ku horisa kumbe ku endliwa, ti silicone rubber chains ti crosslinked hiku ringanela hiku tirhisa ti peroxides  kumbe ti platinum catalysts  kuva ti endla network ya three dimensional. Leswi switiyisisa leswaku leyara ya adhesive yi hundza eka interfacial peeling yo basa  kutlula ku tsandzeka ka cohesive  (ku tshoveka endzeni ka adhesive) ehansi ka ntshikelelo.

Nkomiso

Ku namarhela ka thepi ya PTFE swi tirha hi ndlela leyi landzelaka:

·  Silicone rubber yi tsakamisa vuandlalo naswona yinyika physical adsorption hiku tirhisa matimba ya van der Waals.

·  MQ resin ('swihlala') yi nyika ku namarhela; rhaba ya silicone ('sea') yi nyika ku hlangana.

·  Crosslinking yo ringanela yi tiyisa ku hlangana naswona yi sivela ku tsandzeka ka xinamarheti xa le ndzeni.
